H This f' invention relates to Aa, distributing chute for'co'al bins and 'the like. 1 f "Itisgenera-llythe practice to provide storage'bislfor oalatcoali'ng points for locomotivesf -f The'se bins are usually so constructed that wheltheidelivery chute is opened Ythe coal?automatically?fallsl by gravity: Thesebins are'filled by allowing the coal to run-downa fillig chute; The larger par- -19 ticles of coal gatherconsiderable momentum in traveling fdown the :filling chute with the result that f they will, fall 'forwardly in .the bin. The dust-andsmaller particles or tailings will slowly gravitatedown:thebottom of the' fllling "chute 'with veryv littleA if `any momentum with the result' that such dust and nerparticles ortailingsfwill fallin substantially the" same'sp'ot in theV bin` and finally accumulate'on 'ther'ear` part of the bottom.

'510 ,Consequently when coal is drawn ofi' from a Lbiny'the largerl particles will first escape. Consequently some locomotives'will get all theflar'ger particles of coal;V Finally when thetailingsare reached, it -will-be found that other rlocomotives vget nothing y but tailings which will smother 'the-fire and' impede' gen'- jeration oflsteam. YA? great` `dea-l 'of 'time and consideration has been given'to this problem without anyheretofore? practical solution. Itis an object ofl this invention'to solvethe abovel discussed problem or diiculty by distributing the-tailings' the fco'albinso -that 'there will `be n'o"L accumulation thereofwith lthe'result that each locomotive will receive a proper 'fmizture of'lumps and tailings. VIn other words, this invention serves todi'stribute the* tailings so that peach' discharge from the bin vwill containits proportioned amount oftailings.

In referring to the' drawings, it 1 'will be noted' that in Figures' lto 3 there is illustrate'da coal bin of'jthe single discharge type. This coal Ibin l consists 'of a *front wa'll i 1,",a rear wall-Zandjabottom 3 which vslopes downwardly from the 'rear' wall to the front wall. A coal delivery chute' @extendsfrom` the lower ipart'of the front wall=toward Vwhich the coal naturally gravitates. The upperfpart c of the coal bin isfprovided' with a lling chute 5 and a'stop platespaced forwardly of the end offth'e filling chute. "Such coal'bins'are usually constructed in 'elevatedlpo'sition' 'for the purpose of coalingflocomotives When such a coal bin is filled, the larger particles generally acquire considerable momentum and travel inl advance of' the-tailings .which -85 should be understood as includin'gthe dust and liner particles; Y Hereto'fore, thel tailings would drop substantially in a vertical `direction and 'collecton'the inclined bottom while the heavier particles would drop lJorwardly as illustrated.' f Consequently, the tailings 'werenot properly distributed witlirespe'ctto .the heavier particles. Thev rstlocomotives be discharged.

7, which may be termed a distrilout'er or 'distributing chute, may intercept the tailings falling into the bin. The lower portion ofthe tailings distributing chute 7 is supported by a pair'of braces 8 extending from the front wall ofthe bin. These braces are so designed thatithe lower end of the distributing chute will lie at a suitable oint between the walls 1 and .3 of the bin t at support the coal in order to properly distribute the tailings through the coal. It will `be noted that the distributing chute 7` is generally directed'toward the point of the discharge chute 4, in the bin, so that the tailing will fall upon the lump coa-l. In .the present instance, the distributing chute 7 is illustrated as ofsubstantially the same width as the discharge end of the filling chute. .-The width, however,'rnay be varied as desired; Y. 'i f In Figures 4 and 5, there is shown a double discharge coal-binhaving a central apex 9 in its bottom to provide slopes towardV the two discharge chutes 10 inorder that the coal may naturally gravitate toward such chutes.

In this structure, there are a pair of distributing chutes 7 arranged side by side but oppositely directed, the upper ends of which are supported upon rods 11 carried by the bin. These distributing chutes are supported at their lower portions yby braces 8. attached to the front and side walls 13` and 14 of the bin. The lower ends of these distributing chutes 7 are directed towardtheir respective discharge chutes 10 so as to distribute the tailings over thelump coal'that is in positionrto InFigure 6, there shown `a Acoal bin vhav- ;ing'three discharge'chutes 15,16 and-17. The bottom of this coal bin has two upwardly directed apices 19-tov provide proper gravi- -tatingslopes for the coal in order that lthe coal may naturally gravitate toward the predetermined points defined'y by the discharge outlets or chutes land 17. This coal bin should contain a pair of distributing4 chutes 7 arranged as shown in Figure 4, and a distributing chute as arranged in Figure 1.V V I A,

In Figures v4 and` 6 the upper ends ofthe distributing chutes are` properly positioned beneath thepcoal receivingl chutes v5 and 20 to intercept. the tailings which is sometimes also termed slack coal. v

The coal is usually carried to these storage bins by skip bucket conveyors, and as the coal is dumped upon the receiving chutes it will gravitate into the bins, the courser particles will travel in advanceof the slack coal or tailings. The tailings will` be intercepted by the distributing chutesand will gradually travelon the same. The lump coal falling uponhthevdistributing chutes will roll down V the samefor over the sides thereof and carry some lof the tailings therewith. The tailings that gravitate to the end of the distributing Achute will naturally drop intermediate the lumpcoal adjacent the discharge chute. Consequently therewill always be a uniform mixture of lump 4coal and tailingsdischarged to each locomotive. It-willube appreciated that these distributingchutes do-not take upmuch space nor do they prevent the complete filling of the bins, since the coal can'fall oven-the ends and under the same', V- y. .gz j, y l l I amLawa-rethatniany changesmay., be madel and `numerous detailsv ofxconstructio'n may bevaried through a wide range without departingfrom the'l principles of this inventionA and I, therefore, do not 'purpose limiting the patent granted hereon, otherwisethan necessitated' by the priorart. -V
